Description

Driving License Test System using LFCMC {Driving License Test System using Low Frequency Magnetic Communication}

The present invention relates to a driver license test system using low frequency magnetic communication (LFMC). In particular, the present invention provides a receiver and a transmitter according to the low frequency magnetic communication (LFMC) that can accurately adjust the communication distance without being affected by obstacles, and at the same time to install a transmitter for each course of the driver's license test site, the receiver in the test vehicle It relates to a driver's license test system constructed by mounting.

In the present invention, the low frequency self-communication OUT.ID transmitted from the transmitter mounted for each course and the vehicle ID in the automatic scorer mounted on the test vehicle entering the course are compared to each other to make a reasonable course without overlapping the respective courses. The present invention relates to a technology capable of determining whether the driver's license test has passed by determining whether the vehicle is entered or not and whether the test vehicle proceeds correctly according to a predetermined course order.

The function test during the current driver's license test is to detect driver's inexperience. To this end, various sensors are installed in each course and test vehicle, and the automatic scorer scores the driving results based on the signals generated from these sensors. It is operated as an automated system that determines whether or not it passed.

Because different driving skills have to be tested, the shape of each course is different, so the driver's license scoring system will have to apply different test methods for each course. In addition, because several people have to take the test in one test site, it is necessary to accurately determine the course entered by individual testers to make accurate scoring.

Conventionally, in order to determine a course entered by a tester, a magnet is embedded in a course of a course, and a magnet sensor for detecting the same is attached to a vehicle, and a tachometer which converts the movement of the vehicle into pulses is used. One iron core with the rod magnets in one row in the lengthwise direction is buried in the ground perpendicular to the direction of the vehicle in the course access road. They were buried differently at some distance.

The magnet sensor installed in the test vehicle recognizes that the magnet is embedded in the course entrance and knows that the course has been entered. The test vehicle will run the preset course. Therefore, when the tester calculates the moving distance of the test vehicle by using the tachometer, the tester You know where you are now.

However, in the conventional method, when the test vehicle does not move along the course of a predetermined sequence due to a driver's mistake or starts from a place other than the starting line, the test vehicle operates only the tachometer without passing the magnet embedded in the course entrance. The location of the test vehicle cannot be determined at all.

That is, if the test vehicle does not move along a preset course or starts the test from the middle of the course, the course scored by the automatic scorer differs from the course actually driven by the driver, so that normal scoring cannot be performed. Is not fully automated and requires human intervention.

In the prior art, in order to solve this problem, a much larger number of magnets need to be buried, which is not only excessively expensive but also requires the laying of multiple rows of magnets on the floor due to the structure of the driving test center. There are many places that are difficult in itself, which is unrealistic.

The present invention relates to a driver license test system using low frequency magnetic communication (LFMC). In particular, the present invention provides a receiver and a transmitter according to a low frequency magnetic communication (LFMC) that can accurately adjust the communication distance without being affected by obstacles, and install a transmitter for each course of the driver's license test center and install the receiver in the test vehicle. The purpose of this study is to provide a driver license test system technology.

In the driver's license system of the present invention, the test vehicle accurately enters each course by comparing the low-frequency self-communication OUT.ID transmitted from the transmitter mounted for each course with the vehicle ID in the automatic scorer mounted on the test vehicle entering each course. If the driver's license test is passed, it is determined whether the test vehicle is correctly proceeded according to the rational course sequence without overlapping.

The driver's license test system using the LFMC according to the present invention is installed upward at a predetermined magnetic angle (θ) on the course-by-course driveway of the driver's license test center to transmit a low frequency magnetic signal, but having a unique sender OUT.ID (11). A transmitter 10 which transmits its own sender OUT.ID 11 on a low frequency magnetic signal and transmits it; A receiver 20 mounted downward on the bottom of the test vehicle at a magnetic field angle θ to receive a low frequency magnetic signal of the transmitter 10; And a storage device 40 storing information of a driver in a test vehicle and reasonable course information about the test vehicle, and a test vehicle from a unique caller OUT.ID 11 obtained by the receiver 20 receiving a low frequency magnetic signal. And a controller 30 for acquiring the currently entered course type and comparing it with reasonable course information of the memory device 40 to determine whether there is a course error, and scoring the driver's score accordingly. It is configured to include an automatic scorer (50).

In addition, the driver license test system using the LFMC according to the present invention, when the receiver 20 receives the unique sender OUT.ID 11 in the state of the low frequency magnetic signal, the received information is automatically scored through the control unit 30 as it is. The controller 30 of the automatic scorer 50 compares the vehicle ID 70 stored in the automatic scorer 50 with the received information, and the vehicle 1 does not overlap. It is composed of checking whether data have entered a reasonable course.

In addition, the driver's license test system using the LFMC according to the present invention, the transmitter 10 is set in advance so as to have a predetermined effective coverage is arranged so that each effective coverage for each course of the driver's license test center do not overlap each other; When the receiver 20 receives the plurality of sender OUT.IDs 11, the receiver 20 controls the sender OUT.IDs 11 corresponding to a signal having the strongest signal strength of the low frequency magnetic signal among them under the control of the controller 30. It consists of making a selection.

In addition, the driver's license test method using the LFMC according to the present invention, the test vehicle (1) equipped with a receiver 20 and a driver's license automatic scorer 50 of low-frequency magnetic communication enters each course of the driver's license test site Stage 1; A second low frequency self communication signal carrying its own originating OUT.ID 11 is transmitted from the low frequency self communication transmitter 10 installed in the course-specific access road of the driver's license test center and received by the receiver 20 of the test vehicle. step; A third step of comparing and analyzing the unique originating OUT.ID 11 of the transmitter 10 with the vehicle ID 70 from the received low frequency magnetic communication signal to identify the course currently entered by the test vehicle 1; A fourth step of determining whether the test vehicle enters a duplicate course by comparing a test course in which the outline of each course is set to the test vehicle 1 and the entered course; A fifth step of proceeding with all courses necessary for a driver's license test while proceeding with the first to fourth steps if it is determined that the course is not a duplicated course; And a sixth step of calculating a driving license test result for the test vehicle 1 from the scoring results for each course of the automatic scorer 50.

In addition, the driver's license test method using the LFMC according to the present invention, if it is determined that the entry of the duplicated course as a result of the fourth step, the automatic scorer 30, the step of notifying the error to the test vehicle; do.

According to the present invention, even if the driver makes a mistake when entering the course, an accurate test result is derived, thereby improving reliability.

In addition, according to the present invention, it is possible to set the coverage of the individual transmitter stably, so there is no need to adjust the appropriate range of the transmitter one by one when installing the driver's license test system, there is an advantage that the installation is simple.

In addition, according to the present invention, since the circuit of the transmitter and receiver is simple, the module price is low, and the low power system, the initial installation and maintenance cost of the driver's license test system is low.

In addition, according to the present invention is installed in the harsh external environment in which the driver's license test is performed, there is an advantage that can improve the reliability of the driver's license test result by the stable communication between the transmitter and the receiver through the LFMC.

The present invention relates to a driver's license test system will be described in detail with reference to [1] to [7].

Driver's license test system

The present invention is a driver license test system using a low frequency magnetic communication (LFMC), as shown in the drawing, is installed upward at a predetermined magnetic field angle (θ) on the course-by-course driveway of the driver's license test center to transmit a low frequency magnetic signal, but the unique sender OUT. The transmitter 10 is provided with an ID 11 and carries its own unique sender OUT.ID 11 to the low frequency magnetic signal for transmission. The transmitter 10 is mounted downward on the bottom of the test vehicle at a magnetic field angle θ. The receiver 20 which receives the low frequency magnetic signal of (10) is provided.

The automatic scorer 50 of the driver's license test system includes a memory 40 which stores information of a driver in a test vehicle and reasonable course information about the test vehicle, and a test vehicle from a unique caller OUT.ID 11. The controller 30 may be configured to obtain a currently entered course type, compare it with reasonable course information of the memory device 40, determine a course error, and score a driver's score accordingly.

The items scored by the control unit 30 are stored in the database 82 in the main computer 81 of the control room 80 to process the pass and fail. However, it may be carried out so that the pass and fail in the scorer 50 mounted on the test vehicle 1 is processed, such matters are not important matters in the present invention.

First, reference numeral 100 in FIG. 6 denotes a detection line for detecting whether the vehicle has stepped on the boundary line or not, and a is the ground on which the transmitter can be installed.

First, in the present invention, a low frequency magnetic signal (LFMC) is used so that the receiving module and the transmitting module can normally communicate without being affected by various obstacles in the external environment. Since LFMC can penetrate water, concrete, and plastic rather than magnetic objects, it is more accurate than ultrasonic communication or RF wireless communication, and it excludes cases where communication is disturbed by external environmental factors.

Meanwhile, in the present invention, the transmitter 10 and the receiver 20 are configured by using low frequency magnetic communication (LFMC), and low frequency magnetic communication is judged to be a preferable choice in configuring a driver's license test system according to the present invention. .

First, the method of using the infrared communication, there is a problem that communication is not possible if there is an obstacle between the receiver mounted on the test vehicle and the transmitter installed on the test course. The driver's license test is conducted in a poor external environment, so there may be any obstacle between the receiver and the transmitter, so infrared communication is not suitable for application.

In addition, since infrared communication is affected by natural light, there is a problem that the range of recognition of the course by the individual transmitter is changed due to the change of recognition distance during the day and night, which is not suitable for the driver's license test system.

In addition, when using the ultrasonic communication method, there is a problem that there is a problem between the receiver mounted on the test vehicle and the transmitter installed in the test course, if there is an obstacle or external noise, the driver's license installed in the harsh external environment It is not desirable to apply to test systems.

In addition, the method of using wireless RF communication, if there is an obstacle between the receiver mounted on the test vehicle and the transmitter installed on the test course, the communication is not possible and it is difficult to accurately adjust the communication distance. There is a problem that the range is different, so it is judged that it is not suitable for application to a driver's license test system.

Low frequency magnetic communication (LFMC) has been used in special fields since it has the advantages as described above. Typical applications include automotive air pressure measurement (TPM) and RFID. Commercially available chips for implementing low frequency self-communication (LFMC) are present, for example, MICROCHIP's MCP2030 chip, for example, LFMC itself is a known technology in the field of wireless communication.

The receiver 20 and the transmitter 10 of the present invention may use an industrial type component to operate normally without being influenced by temperature, and it is preferable that the module is waterproofed so that there is no abnormality even in rainy weather.

The calculation also standardizes the shape and size of the coil so that the calling module can cover the defined area. Therefore, the coverage is constant for each product, so there is no need to adjust every time the driver's license test system is installed, which is very convenient. As such, the module of the LFMC transmitter 10 may be installed so that the signal delivery ranges of the transmitters 10 do not overlap with each other so as to cover only a preset range, and the receiver 20 may receive a signal and easily determine its course.

In more detail, in Figure 6 is a plan view of the driver's license course test site. These course test sites are constructed in a variety of forms depending on the area and the installation environment. The most common point is that the course divisions for the test are clear and the length of the course and the width of the boundary are common.

In addition, access routes for each course are set up separately, but after one course, it is possible to enter another course. Therefore, if the transmitter 10 of the present invention is buried on the ground with a separate ID on each side of the course entry path and optionally within each course section.

At this time, the consideration of the installation of the transmitter is to move the test vehicle equipped with the receiver 20 to enter the transmitter 10 and the low-frequency self-communication area installed for each course to detect the outgoing signals of several transmitters 10 at the same time Is likely to be. For the driver's license test, only the signal of the transmitter 10 of the course should be received when entering a course. The signal of the low frequency transmitter 10 is that the radio signal is radiated, so there is a possibility that a common reception area may be generated.

In the present invention, in consideration of these problems, it is the first object to provide enough distance between the transmitter 10 installed on the ground of the course test site so that the low frequency transmission area overlaps with each other as much as possible, and there may be overlapping areas. In addition, the receiver 20 should feel the difference in the strength of the low-frequency transmission signal to adopt a program that recognizes the course of the transmitter 10 that makes the strongest transmission as the course that the vehicle intends to proceed.

For this purpose, in the present invention, the problem can be solved by installing the transmitter 10 in a state spaced at the entrance side of each course as shown in [FIG. 6] and [FIG. 7]. In addition, it is preferable to recognize the point well in the licensed test site different from [6] and [7] and to physically solve by carefully selecting the optimal conditions.

Then, for the transmitter 10 and the receiver 20 in the present invention, the practical benefits that can be obtained by using low frequency magnetic communication will be described. In fact, the low frequency magnetic communication (LFMC) is composed of a simple circuit does not require much effort in manufacturing, the cost burden can be largely solved compared to the conventional detection method. And LFMC can run at low power, so it is less expensive to use.

Although also described, since the signal delivery range of the transmitter 10 using the MCU in both the transmitting module and the receiving module when the LFMC is configured so that the receiving module (= receiver) is the transmitting module (= transmitter) Its position can be accurately determined according to the signal strength of, and if an error occurs in the module by the MCU, the corresponding action can be speeded up.

The transmitter 10 has its own unique OUT. ID 11. Here, OUT. ID 11 denotes the ID of the transmitter 10.

First, if the ID of the transmitter 10 is described, since the transmitter 10 is installed at each driver's license test site for each of the courses and the multiple transmitters 10 will send out signals, these transmitters 10 are each unique. The control unit 30 can accurately detect the location of the location, the detection of the failure, the grading of the license test, and the movement of the non-overlapping vehicle that is out of the prescribed sequence of courses.

On the other hand, the receiver 20 serves to receive the low-frequency magnetic communication transmitted from the transmitter 10 as it is and transmits it to the driver's license test automatic scorer 50 in which the controller 30 exists. The receiver 20 corresponding to the transmitter 10 is also installed in the vehicle 1 together with a driver's license test scorer (= mounting machine) 50 to detect a signal of low-frequency magnetic communication transmitted from the transmitter 10. The controller 30 checks whether the correct signal, that is, the signal of the duplicated OUT.ID 11 is received. That is, since several test vehicles are being tested at the same time, the vehicle ID 70 may need to exist separately from these receivers 20 in order for the automatic scorer 50 to distinguish each test vehicle.

Furthermore, in the present invention, the information of the driver's license tester who has been tested is input to the memory device 40 in the driver's license test automatic scorer 50 mounted on the vehicle 1, and the examinee's resident registration number and examinee's information is used as the tester's information. Numbers, and the order of course tests to be conducted (not a confirmed order, but a reasonable order to avoid duplication).

That is, the automatic scorer 50 installed in the driver's license test site of the present invention comprises a control unit 30 having a vehicle ID 70 and a storage device 40. The storage device 40 includes a driving license test for a driver's license test. Various information and the driver's previous test scores must be registered.

Each examinee who wants to take a driver's license has an age restriction and a unique social security number, and many people take a driver's license at the same time. It is preferable to have a.

Therefore, when input is made to the database 82 through the input device of the main computer 81 installed in the control room 80 of the driver's license test site, this information is loaded into the vehicle 1 by a wireless communication method such as RF communication. The driver's license test automatic scorer 50 is transferred to the storage device 40, and before the driver's license test is performed, the information such as the resident registration number, the examinee's number, and the written test scores is stored in the storage device 40 of the controller 30. It may be entered correctly.

It is already registered in the database 82 of the main computer 81 of the control room 80 of the driver's license center, so it can be imported only when necessary, and information about the course test is always delivered to the main computer 81. This is because the method of storing in the database 82 can also be used.

On the other hand, it should be noted that the "reasonable course information" that each examinee must pass through the course exam is not limited to including the exact order of the course that must pass. In detail, the "T" course should be followed by the "S" course or the reverse.

More preferably, even in the case of the "T" or "S" course, a plurality of courses are installed in the license examination room, but in the present invention, such a predetermined order does not exist. If you have taken the "T" course first, you can go through the "S" or another course. There are no rules that require you to turn the "T" or "S" first. There are a number of "T", " In the course of the letter S, there may not be a rule to turn the letter "T" or the letter "S". Only reasonably, the driver must be able to pass the "T", "S" and other courses in order to pass the test, and all must pass the level to be accepted.

Therefore, it is only necessary to use the vehicle to go through all necessary courses, whether autonomous, following the instructions, or driving. And if you don't need the order of the course, you can go around the course that exists at any location unless you repeat the course you just passed once. After all, the "reasonable course information" referred to in the present invention refers to information that allows all courses that can be passed without overlapping without particular limitation.

In addition, when the receiver 20 receives the unique sender OUT.ID 11 in the state of the low frequency magnetic signal, the receiver 20 provides the received information to the automatic scorer 50 through the control unit 30 as it is, and automatically The control unit 30 of the scorer 50 compares the received information with the vehicle ID 70 stored in the automatic scorer 50, and makes a data whether the vehicle 1 has entered a reasonable course without overlapping. Including checking.

In the present invention, the receiver 20 attached to the vehicle receives the OUT.ID 11, which is a low frequency magnetic signal transmitted from the transmitter 10, and is a control unit in a separate automatic scorer 50, which is also loaded on the vehicle. The signal 30 recognizes this signal and compares and compares the vehicle ID 70 with the data to measure whether a reasonable course has been entered and scores the score based on the score, which is stored in the memory device 40 in the automatic scorer 50. To be automatically input under the control of the controller 30.

The embodiment of the test system of the driver's license test site of the present invention operated as described above will be briefly described. First, the tester's information is input into the database 82 of the control room main computer 81 of the driver's license test center through a separate input device. The information is inputted into the storage device 40 of the driver's license test automatic scorer 50 loaded on the vehicle 1 when necessary. And the vehicle that the input tester will be boarded has a separate vehicle ID (70) in the automatic scorer (50).

In addition, reasonable course information on which the vehicle having the vehicle ID 70 is to be operated is also input. After that, the examinee drives his or her own vehicle (1) and goes through each course. Due to the driver's immaturity or embarrassing environment, the examinee repeatedly runs the course he or she has to go, or leaves the detection line 100 and moves in a different direction. When proceeding to, the receiver 20 receives the OUT.ID 11 transmitted from the transmitter 10 on the ground of the place, which is the control unit 30 of the driver's license test automatic scorer 50 To detect and take action.

Therefore, it is to accurately recognize where the currently running vehicle 1 is located and its position is exactly the non-overlapping course in which it must turn, and to provide a condition for automatically scoring.

As a result, in the present invention, an accurate input of the ID of the receiver 20, the transmitter 10, and the vehicle 1 and the examinee's information are required, and the input controls the signal of the low frequency magnetic communication communicated through the transmitter and the receiver. The function is to be stored in the memory device 40 and scored. The score is thus transferred to the main computer 81 of the control room 80 wirelessly connected to the driver's license test automatic scorer 50, and stored in the database 82 to determine whether the pass or fail of the tester later.

[Preferable installation condition of transmitter and receiver]

2 shows a preferred embodiment in which the transmitter 10 and the receiver 20 are installed to perform LFMC communication. In the driver's license test system, the transmitter 10 is installed for each course and has a unique OUT.ID ( 11) is a device that transmits at regular intervals. The transmission cycle is variable depending on the environment of the test site, and the test vehicle is equipped with a corresponding receiver 20 and moves along its course.

As described above, since a large number of transmitters 10 are installed in the test site, the test vehicle selects the OUT.ID 11 corresponding to the signal having the highest magnitude of the low frequency magnetic signal among them, and is currently driving the course. Recognized as OUT.ID (11), and will be controlled by the control unit 30 accordingly. The signal arrival distance is shown in the attached [Fig. 7]. The receiver signal correspondence of the present invention is proportional to this distance, and it is determined that the strength of the signal is large and small in proportion to the transmitted signal and the received angle.

This low frequency magnetic signal is described in more detail. As shown in FIG. 2, the transmitting antenna of the transmitter 10 is fixed to the inside of the ground by digging the ground at a predetermined angle with the ground.

This is to have a certain directionality to the signal transmitted by the transmitters 10, in the direction (B) located on the antenna plane in Figure 1 is a very weak signal is transmitted, in contrast to the direction perpendicular to the center of the antenna plane In (A), the largest signal is sent out, leading to the farthest progress. The angle at which the transmitter 10 transmits a strong magnetic signal is referred to herein as the magnetic field angle θ.

In addition, the receiver 20 is installed to maintain the same angle as the transmitter 10 because it is advantageous to mutual communication that is installed at an angle facing the transmitter 10 so as to correspond thereto. That is, as shown in FIG. 2, the receiver 20 is installed to look downward at the magnetic field angle θ so that the transmitter 10 is installed to look upward at the magnetic field angle θ. Sensitivity is maximized.

FIG. 2 assumes that a test vehicle equipped with the receiver 20 1 travels course 1, and a test vehicle equipped with the receiver 20 2 travels course 2. Since the transmitter 10 is installed in the course 1 and transmits a signal in the direction of the magnetic angle θ, the receiver 20 is not only stronger than the receiver 20, but also has a good reception direction. The reception sensitivity of 20) 1 would be much better.

After all, the important point in the present invention, the transmitter 10 is set to have a predetermined effective coverage in advance so that each effective coverage for each course of the driver's license test site should be arranged so as not to overlap each other, the receiver 20 is a plurality of senders When the OUT.ID 11 is received, the sender OUT.ID corresponding to the signal having the strongest signal strength of the low-frequency magnetic signal (considering the direction of the magnetic angle θ) among them under the control of the controller 30. It is most preferable to select (11).

The present invention is also characterized by the driver's license test method will be described with reference to [4] to [7].

[Driver's license test method]

■ First step: The test vehicle 1 equipped with the receiver 20 of the low frequency self-communication and the driver's license automatic scorer 50 enters each course of the driver's license test site. That is, as already described in the above-described system, each examinee gets on a vehicle 1 having a separate vehicle ID 70, and a number of separate OUT.IDs 11 are displayed on the ground at the driving license test site. In the input state, he drives his vehicle 1 and starts entry by each course.

■ Second step: The low frequency self communication signal carrying its own originating OUT.ID 11 is transmitted from the low frequency self communication transmitter 10 installed on the course-by-course driveway of the driver's license test center to receive the receiver 20 of the test vehicle. Go through the steps received by. That is, the transmitter 10, which is already installed and fixed on the ground of the license testing station, starts continuous transmission of the signal including its OUT.ID 11 at regular intervals. And the receiver 20 attached to the bottom surface of the vehicle 1 corresponding thereto receives and receives it.

■ Third step: comparing the unique outgoing OUT.ID 11 of the transmitter 10 with the vehicle ID 70 from the received low frequency magnetic communication signal to identify the course that the test vehicle 1 currently enters. Rough

The receiver 20 that has already received the OUT.ID 11 of the transmitter 10 received through the previous step transmits the information under the control of the controller 30 to the driving license test automatic scorer mounted on the vehicle 1 ( It compares with the information recorded in the memory device 40 of 50), and checks whether the entry is made into a non-overlapping course, which is reasonable course information.

In more detail, the information of the occupant who is already being tested is recorded in the storage device 40, which means that the course entering now is actually confirmed by the vehicle ID 11 mounted on the vehicle 1. It is to check if the passenger has already taken the test.

■ 4th step: The test vehicle 1 compares a test course having a course-by-course outline with the entered course, and determines whether the test vehicle enters a duplicate course. That is, although the state has been described to some extent, the present invention is a state in which the rational course information is input to the memory device 40 in the automatic scorer 50 of the vehicle in the most rational manner. If you go inside the course, it will be judged as an invalid entry and continue the course test.

If you enter and exit the "T" course, if you enter another "T" course in the test area, it is judged to be an error. The test is to proceed. In this case, even if there are a plurality of "S" course in the test site, the examiner may enter the "S" course in any section.

The reasonable course information described in the present invention may be referred to as systemized information so that the examinee can take the most convenient and practical test in this test.

■ 5th step: if it is determined that the course is not a duplicated course, proceeding with the first step to the fourth step, proceeding with all courses necessary for the driver's license test; In other words, the examinee who has returned from the non-overlapping course along the correct location and route has passed the course and proceeds as is to take the next course test.

The receiver 20 will then receive the low frequency magnetic signal OUT.ID 11 from the transmitter 10 installed at the entrance of the next course, and the control section 30 will check whether the reception is correct and accordingly the tactics This step is repeated once again, and is controlled and inspected by the controller 30.

As described above, the present invention checks whether the vehicle 1 moves along the non-overlapping course paths in a predetermined order, and proceeds to the final course test. In other words, if the progress of each course is made in succession, such a series of processes are controlled by the control unit 30, it is made automatically.

■ 6th step: The scoring result of each course of the automatic scorer 50 is combined with the information in the database 82 of the main computer 81 to calculate the driving license test result. The end is over.

That is, scores scored in virtually all courses are automatically registered in the automatic scorer 50 embedded in the vehicle 1, and the results of the course test are stored in the control room 80 using wireless communication. Recording is made to the main computer 81. The result is calculated, stored in the database 82, and the examinee who has taken the test determines whether or not the driver's license test has passed.

Then, in the driver's license test method using low frequency self-communication (LFMC), if it is determined that the entry of the duplicated course as a result of the fourth step, the automatic scorer 30 includes notifying an error to the test vehicle. As already mentioned above, it is judged as an error in order to avoid the waste of time and the irrationality that separate scoring is made by returning the redundant course.

That is, when the course is duplicated, the control unit 30 of the automatic scorer 50 of the vehicle goes through a step of buzzing, warning lights and attempting to re-enter the supervisor.

In the third step, the MCU of the control unit 30 receives the signal transmitted from the transmitter 10 to the receiver 20 of the correct vehicle, and the control unit 40 having received this information receives the vehicle ID 70 of the vehicle 1. As a result of comparing and judging, the control unit 30 expresses the examinee and the supervisor through a separate buzzer and a warning. This can be attempted in a number of different ways, the present invention illustrating the voice and visual method in the simplest way.

In other words, a buzzer or flashing a warning light tells you that the current car is entering a roundabout course and allows the test supervisor to take action. That is, when the buzzer and the warning light blink, the control unit 30 detects this and delivers it to the test supervisor through a separate delivery means. The supervisor can go to the examinee to correct the position and take the test again at the correct position. It is. In this process, it is better to notify the test vehicle directly of the error so that the examinee can safely take action.

[Example of the present invention applied to the driving license test site]

An example of installing a low frequency self-communication (LFMC) transmitter 10 according to the present invention for each course of the driver's license test center is shown in FIGS. 6 and 7.

Referring to FIG. 7, a transmitter 10 is installed for each course, and the effective coverage of the transmitter 10 corresponds to an entrance to enter the course and is not overlapped with each other.

In this state, when the test vehicle equipped with the receiver 20 reaches the effective coverage of the transmitter 10 while moving the appropriate course, the receiver 20 determines its course and delivers it to the driver's license function automatic scorer 50. do. The automatic scorer 50 will then perform scoring that fits the course.

Assuming that a driver enters a duplicate course that has already been tested due to a driver's mistake, the receiver 20 will receive a signal from the transmitter 10 of the wrongly entered course, and thus the receiver 20 is a driver's license automatic scorer (50). ) And appropriate action will be taken accordingly.

For example, if you go through the 6th "S" character course of FIG. 6 and then try to enter the 6th "S" character course again, the driver's license function automatic scorer 50 is a wrong course for which the driver is not reasonable. You'll know that you've entered, so you'll take action such as displaying a message saying "You entered the wrong course" with sound or video.

However, if you go through the other "T" course in the figure shown, the test will continue as it is. Since the "T" course is installed in the driver's license test center, the restriction condition that one must be specified must be returned. none. You may choose to take the “T” course from a number of “T” course courses as you wish, or as directed by the examiner. When you take a driver's license test, if there is a course you must pass, you can enter and proceed in any order.

6 and 7 of the present invention is a driving license test site of only one embodiment, so the most reasonable and convenient test will be carried out when applied in the same context to various test sites where various courses are drawn in different forms. It can be.
